Sheldon Cooper's 73 T-Shirt

Sheldon Cooper's 73 T-Shirt Now you can sport the 73 T-Shirt that Sheldon wears because after all 73 is the best number. Why you may ask, well... 73 is the twenty-first prime number. Its mirror, 37, is the twelfth and its mirror, 21, is the product of multiplying (hang on to your hats) 7 and 3.... In binary, 73 is a palindrome: 1-0-0-1-0-0-1, which backwards is 1-0-0-1-0-0-1."  Now you know why 73 is the best number.
